Miniature Precision Parts in Oakdale: Micro Machine Shop

Small parts are not simply scaled down versions of large ones. As features shrink, cutters get thinner, setups get more delicate and measuring gets harder. A hole smaller than a pencil lead behaves differently from a hole you can drill with a standard bit. Buyers around Oakdale who need very small components often find that the choice of shop matters more than the choice of material. Micro Machine Shop is listed here for CNC milling, CNC turning, Swiss machining, plastics machining, miniature parts, medical work, Rexolite and broaching. This page explains what to think about when ordering tiny parts.

What counts as miniature

There is no single definition. In practice, miniature machining refers to parts that are small enough that standard tooling and holding methods struggle. Think of tiny pins, fittings, connectors, probes and housings. If your part fits on a fingertip, it is worth asking whether the shop does this work.

Swiss screw machining

A Swiss style lathe supports the work close to the cutting point, so small slender parts do not flex. It can produce small round parts quickly and repeatably, including short runs. It is common for medical and electronic components. Many Swiss machines can also mill and drill in the same cycle.

Milling small features

Tiny end mills and drills break easily and need gentle cuts. That makes small features slower to machine than their size suggests. A part with many tiny holes may cost more than a larger part with a few big ones. Buyers can reduce cost by limiting small features to those that matter.

Deburring and edge quality

Burrs are small ridges left by cutting. On a miniature part, a burr can be as large as a feature itself. Deburring, including methods suited to tiny parts, is a real step in the job. If edge condition matters for your part, mention it.

Rotary broaching

Broaching can create a hex, a square or another non round hole or shape in a single operation. Rotary broaching on a lathe is a common way to add such a shape to a turned part. It is useful for small drive features.

Plastics and Rexolite

Plastics are common in electronic and medical parts because they insulate and resist chemicals. Rexolite is a rigid plastic used in some microwave and optical applications. Machining it requires attention to heat and to surface quality. If your part uses a specific plastic, name it exactly.

Medical work

Medical components often call for close tolerances, clean finishes and traceability. Ask about material certifications and any cleaning or packaging requirements early.

Details to send

• Drawing with the smallest features highlighted
• Material and grade
• Tolerances on critical dimensions
• Quantity and expected repeat orders
• Cleaning, deburring and packaging notes

Why a small part needs a clear print

On miniature work, one unclear dimension can lead to a batch of unusable parts. A good print, supplied in a common file format, and a short note about the critical features reduce that risk. Buyers in Oakdale and elsewhere should expect to be asked a few questions.
